A.2 Advanced Load Balancing
We will describe Inbound Load Balancing using “Weighted round robin” algorithm for three Internet servers:
1. Web server, www.example.com, using WAN1 – WAN2, with ratio of 1:2
2. FTP server, ftp.example.com, using WAN1 –WAN4, with ration of 1:2:3:4
3. Mail server, mail.example.com , using WAN3 & WAN4, with ratio of 3:4
The ratio of 1:2 means that every return of IP address from WAN1, there will be two returned IP addresses
from WAN2 for the DNS request.
For the Load Balancing “Weighted round robin” algorithm, you should specify the data rate of each individual
WAN ports.
„ Define the WAN speed
„
In Bandwidth Usage page,
select the WAN port and enter
the specific Download and
Upload bandwidth. The
bandwidth must be the correct
value provided by ISP, or the
load balance function might
not work properly.
Do the same configuration for
the other WAN ports.
